How to view the php file which is located in hadoop path?

I have copied my files using hadoop in the following path "/user/hadoop/input" path. Now i need to open the "index.php" file which located in the above path, so i configure that path in apache. Then i tried in Ubuntu using vim 000-default and edit the below two lines.

DocumentRoot /user/hadoop/input
<Directory /user/hadoop/input>

But my "index.php" not working because file(index.php) not viewed, Just throw an following error.
